| 2 | Can acupuncture therapy reduce preoperative anxiety?A systematic review and meta-analysis显示文摘Background:Acupuncture therapy has shown promise for effectively relieving preoperative anxiety.Nevertheless,previous findings from randomized controlled trials(RCTs)are inconsistent and must be examined in detail.Objective:This study systematically evaluates the efficacy and safety of acupuncture therapy for preoperative anxiety as well as the quality of evidence supporting this application.Search strategy:The China National Knowledge Infrastructure Database,Wanfang Data Journal Database,Chinese Biomedical Literature Database,Chongqing VIP,Embase,Pub Med and Cochrane Library Databases were queried from their inception to 19,February 2020,using keywords such as“acupuncture therapy,”“preoperative”and“anxioty.”Manual searches expanded the search breadth and included conference abstracts and other reference lists.Inclusion criteria:RCTs were included in the current study if they contained a comparison between a group of anxiety patients that received acupuncture therapy and a control group that received sham acupuncture.Data extraction and analysis:Literature was reviewed,and various articles were selected using the Note Express 3.2.0 software.Two researchers independently screened and extracted data and evaluated the risk of bias in the included studies.The Rev Man 5.3 software was used for data aggregation and the Grades of Recommendation,Assessment,Development and Evaluation(GRADE)assessment was used to evaluate the quality of the study outcomes.Results:Twelve studies were included in the review,containing a total of 916 patients.Meta-analysis showed that,compared with the control group,patients who received acupuncture therapy had reduced State-Trait Anxiety Inventory Scale(STAI-S)score(mean difference[MD]=–9.07,95%confidence interval[CI][–13.19 to–4.96],P<0.0001)and Visual Analogue Scale(VAS)score(MD=–1.37,95%CI[–2.29 to–0.45],P=0.003).However,for the Hamilton Anxiety Scale(HAMA)score,there was no difference between the two groups(MD=–3.98,95%CI[–12.89 to 4.92],P=0.38).Further,the GRADE assessment demonstrated that the STAI-S was of moderate quality,the VAS of low quality and the HAMA of very low quality.Conclusion:Acupuncture therapy may be able to decrease anxiety in preoperative patients,but the results need to be further verified due to the small sample sizes and the low quality of evidence to date. | Qiu-yu Tong Ran Liu Kun Zhang Yuan G ao Guang-wei Cui Wei-dong Shen | 2021 | Journal of Integrative Medicine2021,19,1: | 15 |
| 3 | Influence of temperature on the characteristics of aerobic granulation in sequencing batch airlift reactors显示文摘Aerobic granular sludge was cultivated in sequencing batch airlift reactors(SBAR) at 25,30,and 35°C,respectively.The effect of temperature on the granules characteristics was analyzed and the microbial community structures of the granules were probed using scanning electron microscope(SEM) and polymerase chain reaction-denaturing gradient gel electrophoresis(PCR-DGGE).The results showed that 30°C is optimum for matured granule cultivation,where the granules had a more compact structure,better settling ability and higher bioactivity,the oxygen utilization rate(OUR) reached 1.14 mg O2/(g MLVSS.min) with COD removal rate of 97% and TP removal rate of 75%.The removal effciency of NH3-N increased from 68.5% to 87.5% along with the temperature increment from 25 to 35°C.The DGGE profiles revealed that the microbial community structure at 25°C showed the least similarity with those at other temperatures.The sequencing results indicated that the majority of dominant microbes belonged to Actinobacteria and Proteobacterium.Thermomonas sp.,Ottowia sp.and Curtobacterium ammoniigenes might play important roles at different temperatures,respectively. | SONG Zhiwei REN Nanqi ZHANG Kun TONG Longyan | 2009 | Journal of Environmental Sciences2009,21,3: | 13 |
| 4 | Effects of professional rehabilitation training on the recovery of neurological function in young stroke patients显示文摘Young stroke patients have a strong desire to return to the society,but few studies have been conducted on their rehabilitation training items,intensity,and prognosis.We analyzed clinical data of young and middle-aged/older stroke patients hospitalized in the Department of Neurological Rehabilitation,China Rehabilitation Research Center,Capital Medical University,China from February 2014 to May 2015.Results demonstrated that hemorrhagic stroke(59.6%) was the primary stroke type found in the young group,while ischemic stroke(60.0%)was the main type detected in the middle-aged/older group.Compared with older stroke patients,education level and incidence of hyperhomocysteinemia were higher in younger stroke patients,whereas,incidences of hypertension,diabetes,and heart disease were lower.The average length of hospital stay was longer in the young group than in the middle-aged/older group.The main risk factors observed in the young stroke patients were hypertension,drinking,smoking,hyperlipidemia,hyperhomocysteinemia,diabetes,previous history of stroke,and heart disease.The most accepted rehabilitation program consisted of physiotherapy,occupational therapy,speech therapy,acupuncture and moxibustion.Average rehabilitation training time was 2.5 hours/day.Barthel Index and modified Rankin Scale scores were increased at discharge.Six months after discharge,the degree of occupational and economic satisfaction declined,and there were no changes in family life satisfaction.The degrees of other life satisfaction(such as friendship) improved.The degree of disability and functional status improved significantly in young stroke patients after professional rehabilitation,but the number of patients who returned to society within 6 months after stroke was still small. | Chao-jin-zi Li Xiao-xia Du Kun Yang Lu-ping Song Peng-kun Li Qiang Wang Rong Sun Xiao-ling Lin Hong-yu Lu Tong Zhang | 2016 | Neural Regeneration Research2016,11,11: | 11 |
| 5 | Effect of Integrated Chinese and Western Medicine Therapy on Severe Hand, Foot and Mouth Disease: A Prospective, Randomized, Controlled Trial显示文摘Objective: To evaluate the efficacy and safety of Chinese medicine(CM) plus Western medicine(WM) in the treatment of pediatric patients with severe hand, foot and mouth disease(HFMD) by conducting a prospective, controlled, and randomized trial. Methods: A total of 451 pediatric patients with severe HFMD were randomly assigned to receive WM therapy alone(224 cases, WM therapy group) or CM [Reduning Injection(热毒宁注射液) or Xiyanping Injection(喜炎平注射液)] plus WM therapy(227 cases, CM plus WM therapy group) for 7–10 days, according to a web-based randomization system. The primary outcome was fever clearance time, which was presented as temperature decreased half-life time. The secondary outcomes included the rate of rash/herpes disappearance within 120 h, as well as the rate for cough, runny nose, lethargy and weakness, agitation or irritability, and vomiting clearance within 120 h. The drug-related adverse events were also recorded. Results: The temperature decreased half-life time was 40.4 h in the WM therapy group, significantly longer than 27.2 h in the CM plus WM therapy group(P<0.01). Moreover, the rate for rash/herpes disappearance within 120 h was 43.6%(99/227) in the CM plus WM therapy group, significantly higher than 29.5%(66/224) in the WM therapy group(P<0.01). In addition, the rate for cough, lethargy and weakness, agitation or irritability disappearance within 120 h was 32.6%(74/227) in the CM plus WM therapy group, significantly higher than 19.2%(43/224) in the WM therapy group(P<0.01). No drug-related adverse events were observed during the course of the study. Conclusions: The combined CM and WM therapy achieved a better therapeutic efficacy in treating severe HFMD than the WM therapy alone. Reduning or Xiyanping Injections may become an important complementary therapy to WM for relieving the symptoms of severe HFMD. | LI Xiu-hui LI Shuang-jie XU Yi WEI Dan SHI Qing-sheng ZHU Qing-xiong YANG Tong DING Jian-bo TIAN Yi-mei HUANG Ji-han WANG Kun WEN Tao ZHANG Xi | 2017 | Chinese Journal of Integrative Medicine2017,23,12: | 10 |
| 6 | The positive function of selenium supplementation on reducing nitrate accumulation in hydroponic lettuce(Lactuca sativa L.)显示文摘High nitrate(NO_3^- ) in vegetables, especially in leaf vegetables poses threaten to human health. Selenium(Se) is an important element for maintaining human health, and exogenous Se application during vegetable and crop production is an effective way to prevent Se deficiency in human bodies. Exogenous Se shows positive function on plant growth and nutrition uptake under abiotic and/or biotic stresses. However, the influence of exogenous Se on NO_3^- accumulation in hydroponic vegetables is still not clear. In the present study, hydroponic lettuce plants were subjected to six different concentrations(0, 0.1, 0.5, 5, 10 and 50 μmol L–1) of Se as Na2 Se O3. The effects of Se on NO_3^- content, plant growth, and photosynthetic capacity of lettuce(Lactuca sativa L.) were investigated. The results showed that exogenous Se positively decreased NO_3^- content and this effect was concentration-dependent. The lowest NO_3^- content was obtained under 0.5 μmol L–1 Se treatment. The application of Se enhanced photosynthetic capacity by increasing the photosynthesis rate(Pn), stomatal conductance(Cs) and the transpiration efficiency(Tr) of lettuce. The transportation and assimilation of NO_3^- and activities of nitrogen metabolism enzymes in lettuce were also analysed. The NO_3^- efflux in the lettuce roots was markedly increased, but the efflux of NO_3^- from the root to the shoot was decreased after treated with exogenous Se. Moreover, Se application stimulated NO_3^- assimilation by enhancing nitrate reductase(NR), nitrite reductase(Ni R), glutamine synthetase(GS) and glutamate synthase enzyme(GOGAT) activities. These results provide direct evidence that exogenous Se shows positive function on decreasing NO_3^- accumulation via regulating the transport and enhancing activities of nitrogen metabolism enzyme in lettuce. We suggested that 0.5 μmol L–1 Se can be used to reduce NO_3^- content and increase hydroponic lettuce yield. | LEI Bo BIAN Zhong-hua YANG Qi-chang WANG Jun CHENG Rui-feng LI Kun LIU Wen-ke ZHANG Yi FANG Hui TONG Yun-xin | 2018 | Journal of Integrative Agriculture2018,17,4: | 9 |

| 8 | Microstructures,micro-segregation and solidification path of directionally solidified Ti-45Al-5Nb alloy显示文摘To investigate the effect of solidification parameters on the solidification path and microstructure evolution of Ti-45Al-5Nb(at.%) alloy, Bridgman-type directional solidification and thermodynamics calculations were performed on the alloy. The microstructures, micro-segregation and solidification path were investigated.The results show that the β phase is the primary phase of the alloy at growth rates of 5-20 μm·s^(-1) under the temperature gradients of 15-20 K·mm^(-1), and the primary phase is transformed into an α phase at relatively higher growth rates(V >20 μm·s^(-1)). The mainly S-segregation and β-segregation can be observed in Ti-45Al-5Nb alloy at a growth rate of 10 μm·s^(-1) under a temperature gradient of 15 K·mm^(-1). The increase of temperature gradient to 20 K·mm^(-1) can eliminate β-segregation, but has no obvious effect on S-segregation. The results also show that 5 at.% Nb addition can expand the β phase region, increase the melting point of the alloy and induce the solidification path to become complicated. The equilibrium solidification path of Ti-45Al-5Nb alloy can be described as L L→β L+β L+β→αα+β_R β→ααα→γα+γα→α_2+γγ_R+(α_2+γ), in which β_R and γ_R mean the residual β and | Liang-shun Luo Tong Liu Kun Li Yan-qing Su Jing-jie Guo Heng-zhi Fu | 2016 | China Foundry2016,13,2: | 7 |
| 9 | Light absorption properties and potential sources of brown carbon in Fenwei Plain during winter 2018–2019显示文摘A distinctive kind of organic carbon aerosol that could absorb ultraviolet-visible radiation is called brown carbon(Br C),which has an important positive influence on radiative budget and climate change.In this work,we reported the absorption properties and potential source of Br C based on a seven-wavelength aethalometer in the winter of 2018–2019 at an urban site of Sanmenxia in Fenwei Plain in central China.Specifically,the mean value of Br C absorption coefficient was 59.6±36.0 Mm^(-1) at 370 nm and contributed 37.7%to total absorption,which made a significant impact on visibility and regional environment.Absorption coefficients of Br C showed double-peak pattern,and Br C had shown small fluctuations under haze days compared with clean days.As for the sources of Br C,Br C absorption coefficients expressed strong correlations with element carbon aerosols and primary organic carbon aerosols,indicating that most of Br C originated from primary emissions.The linear correlations between trace metal elements(K,As,Fe,Mn,Zn,and Pb)and Br C absorption coefficients further referred that the major sources of Br C were primary emissions,like coal burning,biomass burning,and vehicle emissions.The moderate relationship between Br C absorption coefficients and secondary organic aerosols suggested that secondary production of Br C also played an important role.The 120 hr backward air mass trajectories analysis and concentration-weighted trajectories analysis were also used to investigate potential sources of Br C in and around this area,which inferred most parts of Br C were derived from local emissions. | Wenyu Zhang Weigang Wang Jie Li Shuangliang Ma Chaofan Lian Kun Li Bo Shi Mingyuan Liu Yanyu Li QingQing Wang Yele Sun Shengrui Tong Maofa Ge | 2021 | Journal of Environmental Sciences2021,33,4: | 6 |
| 10 | Parallel selection of distinct Tof5 alleles drove the adaptation of cultivated and wild soybean to high latitudes显示文摘Photoperiod responsiveness is a key factor limiting the geographic distribution of cultivated soybean and its wild ancestor.In particular,the genetic basis of the adaptation in wild soybean remains poorly understood.In this study,by combining whole-genome resequencing and genome-wide association studies we identified a novel locus,Time of Flowering 5(Tof5),which promotes flowering and enhances adaptation to high latitudes in both wild and cultivated soybean.By genomic,genetic and transgenic analyses we showed that Tof5 en-codes a homolog of Arabidopsis thaliana FRUITFULL(FUL).Importantly,further analyses suggested that different alleles of Tof5 have undergone parallel selection.The Tof5H1 allele was strongly selected by humans after the early domestication of cultivated soybean,while Tof5H2 allele was naturally selected in wild soybean,and in each case facilitating adaptation to high latitudes.Moreover,we found that the key flowering repressor E1 suppresses the transcription of Tof5 by binding to its promoter.In turn,Tof5 physically associates with the promoters of two important FLOWERING LOCUS T(FT),FT2a and FT5a,to upregulate their transcription and promote flowering under long photoperiods.Collectively,ourfindings provide insights into how wild soybean adapted to high latitudes through natural selection and indicate that cultivated soybean underwent changes in the same gene but evolved a distinct allele that was artificially selected after domestication. | Lidong Dong Qun Cheng Chao Fang Lingping Kong Hui Yang Zhihong Hou Yongli Li Haiyang Nan Yuhang Zhang Qingshan Chen Chunbao Zhang Kun Kou Tong Su Lingshuang Wang Shichen Li Haiyang Li Xiaoya Lin Yang Tang Xiaohui Zhao Sijia Lu Baohui Liu Fanjiang Kong | 2022 | Molecular Plant2022,15,2: | 5 |
| 11 | Characteristics of deep drainage and soil water in the mobile sandy lands of Inner Mongolia, northern China显示文摘Quantification of deep drainage and the response of soil water content to rainfall patterns are critical for an effective management strategy of soil water conservation and groundwater utilization. However, there has been little information on how rainfall characteristics influence soil water dynamics and deep drainage in mobile sandy lands. We used an underground chamber to examine the responses of deep drainage and soil water content in mobile sandy lands to rainfall characteristics in Inner Mongolia during the growing seasons of 2010, 2011 and 2012. Results showed that rainfall in this area was dominated by small events(≤5 mm), which increased soil water content in the surface soil layers(0–40 cm), but did not increase soil water content in the deeper soil layers(greater than 40 cm). Soil water content at the 0–100 cm depth increased significantly when the total amount of rain was >20 mm. Rainfall amount, intensity and the duration of dry intervals were significantly related to the soil water content in different soil layers. Deep drainage was significantly correlated with rainfall amount and intensity, but not with the duration of dry intervals. The coefficients of deep drainage in the mobile sandy lands ranged from 61.30% to 67.94% during the growing seasons. Our results suggested that rainfall infiltration in the mobile sandy lands had considerable potential to increase soil water storage while recharging the groundwater in this region. | Xin Ping LIU Yu Hui HE Xue Yong ZHAO Tong Hui ZHANG La Mei ZHANG Yun Hua MA Shu Xia YAO Shao Kun WANG Shui Lian WEI | 2015 | Journal of Arid Land2015,7,2: | 4 |
| 12 | Effects of Structural Changes in Subchondral Bone on Articular Cartilage in a Beagle Dog Model显示文摘Objective Using MR T2-mapping and histopathologic score for articular cartilage to evaluate the effect of structural changes in subchondral bone on articular cartilage. Methods Twenty-four male Beagle dogs were randomly divided into a subchondral bone defect group(n = 12) and a bone cement group(n = 12). Models of subchondral bone defectin the medial tibial plateau and subchondral bone filled with bone cement were constructed. In all dogs, the left knee joint was used as the experimental sideand the right knee as the sham side. The T2 value for articular cartilage at the medial tibial plateau was measured at postoperative weeks 4, 8, 16, and 24. The articular cartilage specimens were stained with hematoxylin and eosin, and evaluated using the Mankin score. Results There was a statistically significant difference(P < 0.05) in Mankin score between the bone defect group and the cement group at postoperative weeks 16 and 24. There was a statistically significant difference in the T2 values between the bone defect group and its sham group(P < 0.05) from week 8, and between the cement group and its sham group(P < 0.05) from week 16. There was significant difference in T2 values between the two experimental groups at postoperative week 24(P < 0.01). The T2 value for articular cartilage was positively correlated with the Mankin score(ρ = 0.758, P < 0.01). Conclusion Structural changes in subchondral bone can lead to degeneration of the adjacent articular cartilage. Defects in subchondral bone cause more severe degeneration of cartilage than subchondral bone filled with cement. The T2 value for articular cartilage increases with the extent of degeneration. MR T2-mapping images and the T2 value for articular cartilage can indicate earlycartilage degeneration. | YAN Dong LIU Tong Xi LIU Bao Yue WANG Ling QIAN Zhan Hua CHENG Xiao Guang LI Kun Cheng | 2017 | Biomedical and Environmental Sciences2017,30,3: | 4 |
| 13 | Multicenter phaseⅡstudy of apatinib single or combination therapy in HER2-negative breast cancer involving chest wall metastasis显示文摘Objective:Breast cancer(BC)with chest wall metastasis(CWM)usually shows rich neovascularization.This trial explored the clinical effect of apatinib on human epidermal growth factor receptor 2(HER2)-negative advanced BC involving CWM.Methods:This trial involved four centers in China and was conducted from September 2016 to March 2020.Patients received apatinib 500 mg/d[either alone or with endocrine therapy if hormone receptor-positive(HR+)]until disease progression or unacceptable toxicity.Progression-free survival(PFS)was the primary endpoint.Results:We evaluated 26 patients for efficacy.The median PFS(mPFS)and median overall survival(mOS)were4.9[range:2.0-28.5;95%confidence interval(95%CI):2.1-8.3]months and 18(range:3-55;95%CI:12.9-23.1)months,respectively.The objective response rate(ORR)was 42.3%(11/26),and the disease-control rate was76.9%(20/26).In the subgroup analysis,HR+patients compared with HR-negative patients had significantly improved mPFS of 7.0(95%CI:2.2-11.8)months vs.2.3(95%CI:1.2-3.4)months,respectively(P=0.001);and mPFS in patients without or with chest wall radiotherapy was 6.4(95%CI:1.6-19.5)months vs.3.0(95%CI:1.3-4.6)months,respectively(P=0.041).In the multivariate analysis,HR+status was the only independent predictive factor for favorable PFS(P=0.014).Conclusions:Apatinib was highly effective for BC patients with CWM,especially when combined with endocrine therapy.PFS improved significantly in patients with HR+status who did not receive chest wall radiotherapy.However,adverse events were serious and should be carefully monitored from the beginning of apatinib treatment. | Huiping Li Cuizhi Geng Hongmei Zhao Hanfang Jiang Guohong Song Jiayang Zhang Yaxin Liu Xinyu Gui Jing Wang Kun Li Zhongsheng Tong Fangyuan Zhao Junlan Yang Guoliang Chen Qianyu Liu Xu Liang | 2021 | Chinese Journal of Cancer Research2021,33,2: | 4 |
| 14 | Boosting triplet self-trapped exciton emission in Te(IV)-doped Cs_(2)SnCl_(6) perovskite variants显示文摘Perovskite variants have attracted wide interest because of the lead-free nature and strong self-trapped exciton (STE) emission. Divalent Sn(II) in CsSnX3 perovskites is easily oxidized to tetravalent Sn(IV), and the resulted Cs2SnCl6 vacancy-ordered perovskite variant exhibits poor photoluminescence property although it has a direct band gap. Controllable doping is an effective strategy to regulate the optical properties of Cs2SnX6. Herein, combining the first principles calculation and spectral analysis, we attempted to understand the luminescence mechanism of Te4+-doped Cs2SnCl6 lead-free perovskite variants. The chemical potential and defect formation energy are calculated to confirm theoretically the feasible substitutability of tetravalent Te4+ ions in Cs2SnCl6 lattices for the Sn-site. Through analysis of the absorption, emission/excitation, and time-resolved photoluminescence (PL) spectroscopy, the intense green-yellow emission in Te4+:Cs2SnCl6 was considered to originate from the triplet Te(IV) ion 3P1→1S0 STE recombination. Temperature-dependent PL spectra demonstrated the strong electron-phonon coupling that inducing an evident lattice distortion to produce STEs. We further calculated the electronic band structure and molecular orbital levels to reveal the underlying photophysical process. These results will shed light on the doping modulated luminescence properties in stable lead-free Cs2MX6 vacancy-ordered perovskite variants and be helpful to understand the optical properties and physical processes of doped perovskite variants. | Ruosheng Zeng Kun Bai Qilin Wei Tong Chang Jun Yan Bao Ke Jialuo Huang Liushun Wang Weichang Zhou Sheng Cao Jialong Zhao Bingsuo Zou | 2021 | Nano Research2021,14,5: | 4 |
| 15 | Aboveground biomass and its spatial distribution pattern of herbaceous marsh vegetation in China显示文摘Herbaceous marsh is the most widely distributed type of marsh wetland ecosystem,and has important ecological functions such as water conservation,climate regulation,carbon storage and fixation,and sheltering rare species.The carbon sequestration function of herbaceous marsh plays a key role in slowing climate warming and maintaining regional environmental stability.Vegetation biomass is an important index reflecting the carbon sequestration capacity of wetlands.Investigating the biomass of marsh vegetation can provide a scientific basis for estimating the carbon storage and carbon sequestration capacity of marshes.Based on field survey data of aboveground biomass of herbaceous marsh vegetation and the distribution data set of marsh in China,we analyzed the aboveground biomass and its spatial distribution pattern of herbaceous marsh on a national scale for the first time.The results showed that in China the total area of herbaceous marsh was 9.7×10^(4) km^(2),the average density of aboveground biomass of herbaceous marsh vegetation was 227.5±23.0 g C m-2(95%confidence interval,the same below),and the total aboveground biomass was 22.2±2.2 Tg C(1 Tg=1012 g).The aboveground biomass density of herbaceous marsh vegetation is generally low in Northeast China and the Tibetan Plateau,and high in central North China and coastal regions in China.In different marsh distribution regions of China,the average biomass density of herbaceous marsh vegetation from small to large was as follows:temperate humid and semi-humid marsh region(182.3±49.3 g C m^(-2)) | Xiangjin SHEN Ming JIANG Xianguo LU Xingtu LIU Bo LIU Jiaqi ZHANG Xianwei WANG Shouzheng TONG Guangchun LEI Shengzhong WANG Chuan TONG Hangqing FAN Kun TIAN Xiaolong WANG Yuanman HU Yonghong XIE Muyuan MA Shuwen ZHANG Chunxiang CAO Zhichen WANG | 2021 | Science China Earth Sciences2021,64,7: | 4 |

| 17 | Identification of Histoplasma causing an unexplained disease cluster in Matthews Ridge, Guyana显示文摘Here,we report the identification of Histoplasma causing an unexplained disease cluster in Matthews Ridge,Guyana.In March 2019,14 employees of Chongqing Bosai Mining Company,China,working in a manganese mining of Guyana,had unexplained fever,and two of them died.We obtained lung and brain tissues as well as the blood samples from the two deceased cases(patient No.1 and 2),and bronchoscopy lavages and cerebrospinal fluid samples from one severe case(patient No.3),respectively.All samples were tested by pathological examination,high-throughput sequencing,and real-time PCR.Pathological detection showed the presence of spore-like structures in the lung tissue of patient No.1,indicating a fungal infection in this patient.Nanopore sequencing identified the existing of H.capsulatum in the lung tissue sample within 13 h.Next-generation sequencing identified specific fragments of H.capsulatum in all of the samples tested(lung,brain and blood serum from the deceased cases,and plasma from the severe case).Real-time PCR assays did not reveal any viral infection related to transmission from bat feces.We conclude that H.capsulatum was the causative pathogen of this disease cluster based on epidemiologic,clinical,pathological and nucleic acid evidence. | Ji Wang Weimin Zhou Hua Ling Xiaoping Dong Yi Zhang Jiandong Li Yong Zhang Jingdong Song William J.Liu Yang Li Ruiqing Zhang Wei Zhen Kun Cai Shuangli Zhu Dongyan Wang Jinbo Xiao Yigang Tong Wenli Liu Lihua Song Wei Wu Yang Liu Xiang Zhao Ruihuan Wang Sheng Ye Jing Wang Roujian Lu Baoying Huang Fei Ye Wenwen Lei Rongbao Gao Qi Shi Cao Chen Jun Han Wenbo Xu George F.Gao Xuejun Ma Guizhen Wu | 2019 | Biosafety and Health2019,1,3: | 3 |
| 18 | Construction of an efficient genomic editing system with CRISPR/Cas9 in the vector mosquito Aedes albopictus显示文摘Aedes (Stegomyia) albopictus, also known as the Asian tiger mosquito, is a mosquito which originated in Asia. In recent years, it has become increasingly rampant throughout the world. This mosquito can transmit several arboviruses, including dengue, Zika and chikungunya viruses, and is considered a public health threat. Despite the urgent need of genome engineering to analyze specific gene functions, progress in genetical manipulation of Ae. albopictus has been slow due to a lack of efficient methods and genetic markers. In the present study, we established targeted disruptions in two genes, kynurenine hydroxylase (kh) and dopachrome conversion enzyme (yellow), to analyze the feasibility of generating visible phenotypes with genome editing by the clustered regularly interspaced short palindromic repeats (CRISPR)/ CRISPR-associated protein 9 (Cas9) system in Ae. albopictus. Following Cas9 single guide RNA ribonucleoprotein injection into the posterior end of pre-blastoderm embryos, 30%-50% of fertile survivors produced alleles that failed to complement existing kh and yellow mutations. Complete eye and body pigmentation defects were readily observed in GI pupae and adults, indicating successful generation of highly heritable mutations. We conclude that the CRISPR/Cas9-mediated gene editing system can be used mAe. albopictus and that it can be adopted as an efficient tool for genome-scale analysis and biological study. | Tong Liu Wen-Qiang Yang Yu-Gu Xie Pei-Wen Liu Li-Hua Xie Feng Lin Chen-Ying Li Jin-Bao Gu Kun Wu Gui-Yun Yan Xiao-Guang Chen | 2019 | Insect Science2019,26,6: | 3 |
| 19 | Prognostic and incremental value of computed tomography-based radiomics from tumor and nodal regions in esophageal squamous cell carcinoma显示文摘Objective:This study aimed to evaluate the prognostic value of preoperative radiomics and establish an integrated model for esophageal squamous cell cancer(ESCC).Methods:A total of 931 patients were retrospectively enrolled in this study(training cohort,n=624;validation cohort,n=307).Radiomics features were obtained by contrast-enhanced computed tomography(CT)before esophagectomy.A radiomics index was set based on features of tumor and reginal lymph nodes by using the least absolute shrinkage and selection operator(LASSO)Cox regression.Prognostic nomogram was built based on radiomics index and other independent risk factors.The prognostic value was assessed by using Harrell’s concordance index,time-dependent receiver operating characteristics and Kaplan-Meier curves.Results:Twelve radiomic features from tumor and lymph node regions were identified to build a radiomics index,which was significantly associated with overall survival(OS)in both training cohort and validation cohort.The radiomics index was highly correlated with clinical tumor-node-metastasis(cTNM)and pathologic TNM(pTNM)stages,but it demonstrated a better prognostic value compared with cTNM stage and was almost comparable with pTNM stage.Multivariable Cox regression showed that the radiomics index was an independent prognostic factor.An integrated model was constructed based on gender,preoperative serum sodium concentration,pTNM and the radiomics index for clinical usefulness.The integrated model demonstrated discriminatory ability better compared with the traditional clinical-pathologic model and pTNM alone,indicating incremental value for prognosis.Conclusions:CT-based radiomics for primary tumor and reginal lymph nodes was sufficient in predicting OS for patients with ESCC.The integrated model demonstrated incremental value for prognosis and was robust for clinical applications. | Bangrong Cao Kun Mi Wei Dai Tong Liu Tianpeng Xie Qiang Li Jinyi Lang Yongtao Han Lin Peng Qifeng Wang | 2022 | Chinese Journal of Cancer Research2022,34,2: | 3 |
| 20 | Biodegradable Zn–3Cu and Zn–3Cu–0.2Ti alloys with ultrahigh ductility and antibacterial ability for orthopedic applications显示文摘Zinc(Zn) and its alloys have been proposed as biodegradable implant materials due to their unique combination of biodegradability, biocompatibility, and biofunctionality. However, the insufficient mechanical properties of pure Zn greatly limit its clinical application. Here, we report on the microstructure, mechanical properties, friction and wear behavior, corrosion and degradation properties, hemocompatibility, and cytocompatibility of Zn–3 Cu and Zn–3 Cu–0.2 Ti alloys under three different conditions of as-cast(AC),hot-rolling(HR), and hot-rolling plus cold-rolling(HR + CR). The HR + CR Zn–3 Cu–0.2 Ti exhibited the best set of comprehensive properties among all the alloy samples, with yield strength of 211.0 MPa, ultimate strength of 271.1 MPa, and elongation of 72.1 %. Immersion tests of the Zn–3 Cu and Zn–3 Cu–0.2 Ti alloys in Hanks’ solution for 3 months indicated that the AC samples showed the lowest degradation rate,followed by the HR samples, and then the HR + CR samples, while the HR + CR Zn–3 Cu exhibited the highest degradation rate of 23.9 m/a. Friction and wear testing of the Zn–3 Cu and Zn–3 Cu–0.2 Ti alloys in Hanks’ solution indicated that the AC samples showed the highest wear resistance, followed by the HR samples, and then the HR + CR samples, while the AC Zn–3 Cu–0.2 Ti showed the highest wear resistance.The diluted extracts of HR + CR Zn–3 Cu and Zn–3 Cu–0.2 Ti at a concentration of ≤25 % exhibited noncytotoxicity. Furthermore, both the HR + CR Zn–3 Cu and Zn–3 Cu–0.2 Ti exhibited effective antibacterial properties against S. aureus. | Jixing Lin Xian Tong Kun Wang Zimu Shi Yuncang Li Matthew Dargusch Cuie Wen | 2021 | Journal of Materials Science & Technology2021,,9: | 3 |
